COlN -CONTROLLED ELECTRIC BATTERY.

SPECIFICATION forming part of Letters Fatent No. 712,781, dated November4, 1902.

Application filed August 6, 1901. Serial No. 71.025. (No model.)

To all whom, it may concern:

Be it known that I,FRANOIS DUWE, a citizen of the United States, and aresident of New York, county of New York, and State of New York, haveinvented certain new and useful Improvements in Coin-Controlled ElectricBatteries, of which the following is a specification, reference beinghad to the accompanying drawings, forming a part thereof, in whichsimilar characters of reference indicate corresponding parts.

This invention relates to coin-controlled electric batteries.

The object of the invention is to produce a coin-controlled electricbattery which may be used to try the strength of the nerves of theoperator and for divers similar purposes.

The nature of the invention will be fully understood from the followinggeneral description and the annexed drawings and will be subsequentlypointed out in the claims.

Figure 1 of the accompanying drawings is a vertical-sectional view takenonthe line 3 y of Fig. 2. Fig. 2 is a horizontal sectional view showingsome of the parts, taken on the line m '00 of Fig. 1. Fig. 3 is a detailview showing some of the parts, taken on the line .2 z of Fig. 2. Figs.4c, 5, and 6 are views of details more fully hereinafter described. Fig.7 is a detail sectional view taken on the line 1 1 of Fig. 2.

The whole device is 'inclosed in a case or box, as 1, which may be ofwood or any other post E is fastened upright in the upper compartment,near the back of the case, and extends upward from the partition'2toward the top of the case.

B designates the battery, which may be of any approved construction andis located within the case, as illustrated.

Upon the upright post E is fastened the solenoid F, in which moves thearmature-core P. This core P is moved by the levers H and I. The lever His pivoted to a fixed bearing at h and, upholding the movablecylindrical pole K with one end, is pivoted to the lever I at h. Themiddle part of the lover I is attached to the core I of the solenoid F.The spring 6 holds these parts in normal position. The cylindrical poleL is stationary, with its on this bracket b at 1).

lower endin electrical connection with the bar H These poles, levers,and bar are so connected as to form part of an electric circuit, ashereinafter more fully described. As the cylindrical pole K depressesthe end of the lever H, which is pivoted at h, the core is raised upwardout of the solenoid. As soon as pressure on the cylinder is relaxed thespring 2' draws the core down again. A designates a coin-chute whichwhen a coin is deposited in it conducts such coin down to opposite theopening I) in the lever C. This lever O is pivoted on the stationarybracket 19 at b. The lever B is also pivoted The lever B, which isoverlapped by the lever 0, extends to the cylinder M and isconnectedwith the pistonrod m of this cylinder. This cylinder M, whichis horizontally located in the said case 1 near the partition 2, isnearly air-tight and in it is an air-tight piston m which is moved bythe rod m and the lever B. To facilitate this there is a pivot-joint atb in this lever. The hook-lever O is pivoted at 0 to a stationarybearing. It is formed at one end with a catch 0 which isadapted andarranged to engage the pin 0 on the lever O. The other end of this leverO, which is bent as illustrated, extends to the bar D and is arranged tobe engaged by the collar d of the said bar D. This lever is held innormal position by the spring 0 The spring 0 holds the lever O in normalposition, and the spring 0 holds the lever B in normal position, as willbe more fully hereinafter described.

On the lever B is fastened a bracket N. This'bracket is formed of aplate of conducting material bent at right'angles through the middle, sothat when so fastened on the said lever one part of said bracket willextend upward from said lever at right angles thereto. Upon one side ofthis extension is fixed a surface 25 of non-conducting material. On theother side thereof the conducting material is left uncovered. Rdesignates a hanger, which is fixed on a stationary support inthe saidcase a little above the line of motion of the said lever B. Upon thishanger is fixed the plate N, which depends downward, across, and nearlyinto the line of motion of the said lever B. This is a resilient plate.It is so bent and arranged that when the lever B moves in one directionthe non-conducting side i of the extension of the bracket N will slidealong againstthe said plate; but when the said lever moves in theopposite direction the conducting side of the bracket extension willslide along in contact with the said plate N. This partof the device,which has'proper electric connections, operates as a circuitcloser, allof which will be more fully hereinafter described.

D designates a sliding bar, which is located in the case so that one endrests near the lever C, directly opposite the opening I).

This bar is of such size that it could be pushed through the saidopening without moving the lever. On this bar is formed a collar (1 toact upon the hook-lever 0. There is a spring d, arranged to hold thisbar in normal position, and the end of the bar extends outside of thecase.

At the top of the case and extending above it are located the movablecylindrical pole K,alreadydescribed, and the stationary cylindrical poleL. These two cylindrical poles K and L are electrically connected withthe battery B by a circuit composed in part of parts of the mechanismand in part by electric conduits connecting said parts and connectingsaid cylinders therewith, as is illustrated in the drawings.

In order to show the strength of the electric current and the positionof the core P in the solenoid F, a scale (designated by i) is fastenedon the solenoid parallel to the line of motion of said core P, so thatas the pole K is moved and by its connections, as hereinbeforedescribed, moves the core an index-point i attached to the said core,moves therewith on the said scale, giving the proper indications. In theexample of my invention here given a slot is cut in the scale-plate,through which the index-point extends over the graduations of the scale.This may, however, be accomplished in any other convenient and availableway, and the index-point may be attached to the core in any approved andavailable way.

\Vhen a coin has been deposited in the upper end of the coin-chute A, itslides down and stops directly behind the opening Z) of the lever O. Theelectric circuit is not now closed, because there is no contact betweenthe parts N and N. As soon as the operator pushesin the slide D itpresses on the coin and carries forward the end of the lever O. Thisalso moves the lever B into the position illustrated in dotted lines.While this is being done the non-conducting side of the bracket N passesthe plate N, the piston is drawn forward in the cylinder M, and thehook-lever O engages the pin 0 of the lever C and temporarily holds saidlever in that position. As soon as the pressure is removed from theslide D by reason of the resilience of the spring at it quickly returnsto its normal position, the coin drops through the hole 4 into a properreceptacle, and the collar cl, engaging the end of the hook-lever O,releases it from the pin 0. As soon as the hook-lever releases the pinthe lever C is drawn by the spring a quickly to its normal position; buton account of the resistance of the air in the cylinder M the lever B,drawn by the spring 0, returns to its normal position slowly. Thismotion of the lever 13 carries the conducting side of the bracket N overthe face of the plate N and closes the circuit, so that if at any timewhile these two parts are so passing each other the operator grasps thecylindrical poles K and L one in each hand he will receive an electriccurrent which will pass through his body from hand to hand. The strengthof the current may be varied by raising or depressing the eylindricalpole K, which draws, as before described, the armature P upward anddownward in the solenoid F. When the lever B has returned so near to itsnormal position that the parts N and N are no longer in contact, theaction ceases. The action may be renewed as often as may be desired byputting in another coin each time and performing the operation beforedescribed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination with a chute to conduct coins; a pivoted lever toreceive such coins; a spring holding said lever in normal position; asliding bar to move said lever and release said coins; a spring holdingsaid bar in normal position; a hook-lever adapted to engage a pin onsaid coin-receiving lever, and temporarily hold said coin-receivinglever; a spring holding said hook-lever in normal po sition; acircuit-closing lever moved by said coin-receiving lever; a springholding said circuit-closing lever in normal position; a circuit-closeroperated by said circuit-closing lever; an air-cylinder; a piston andpistonrod arranged in connection therewith to retard the return motionof said circuit-closing lever; and cause it to move slowly; ofcylindrical poles adapted to convey an electric current into the humanbody; a solenoid; a movable core within said solenoid; lever and springmechanism, connecting said core with one of said poles, so that whensaid pole is moved said core will be moved in said solenoid, to vary thestrength of said current; an electric battery; and electrical conductorsconnecting said parts with each other and with said battery; allsubstantially as and for the purpose set forth.
